make deploy errors out

[stevepiercy]

Following the training successfully from start until it fails at this point:

https://training.plone.org/plone-deployment/deploy.html#using-provided-makefile

$ make deploy
==> Deploy Stack in dev 
error during connect: Get "http://docker.example.com/v1.24/info": command [ssh -l plone -p 2222 -- 127.0.0.1 docker system dial-stdio] has exited with exit status 255, please make sure the URL is valid, and Docker 18.09 or later is installed on the remote host: stderr=plone@127.0.0.1: Permission denied (publickey).

make: *** [deploy] Error 1

I have Docker version 20.10.20.

I have no clue.

FWIW, when I @echo out the command by tweaking the Makefile target, I get:

docker --context dev stack deploy -c stacks/plone.yml plone

I looked in that file, but nothing jumped out at me.

One more data point, I use various named keys in my local ~/.ssh, none of which are named id_rsa. I had pasted the value of vagrant.pub into group_vars/all/users.yml as specified in the training at Configure SSH key. What is the expected value that should be pasted in there and what should it be named in ~/.ssh?

@stevepiercy It sounds like you've configured the VM to authorize access by the holder of the private key that is paired with the public key in vagrant.pub. If this is not your default private key, then you probably need to add explicit ssh configuration to use the right key when connecting to the VM. Something like this in ~/.ssh/config, assuming the private key is in ~/.ssh/vagrant:

Host 127.0.0.1
    IdentityFile ~/.ssh/vagrant

@stevepiercy or if you don't want to change your ssh configuration, it looks like you can specify a key when creating the Docker context: https://stackoverflow.com/questions/63868735/docker-context-how-to-use-specific-ssh-key

Revisiting this. Changing ~/.ssh/config to the following worked for make provision:

Host 127.0.0.1
    IdentityFile ~/.ssh/vagrant

I'm more familiar with that technique. I can also toggle it, if it interferes with other development. Also the SO comments warn it might not work with Docker Compose, but I can always switch to it if needed.

I was able to proceed through make run-playbook, but now I don't know what to do next. I think that is more of a Training issue now, something that was said in person but not in writing 😢 .

Closing this issue here, and opening one in training. Thank you for your help @davisagli!
